Maintaining the PHIUS Certified Builder Credential 

nominal maintenance fee will be billed on a yearly basis starting on January 15, 2018.

(For example a CPHC® who is also a Certified Builder, will be subject to a single maintenance fee.)

The fee will help maintain and improve the listing database and assist in the development of the continuing education programs for all professionals.

PHIUS Certified Builders can maintain/extend their certification status through either one of the following methods:

1. Build a PHIUS+ Certified Passive Building Project

Successfully building a project within three years after the professional’s certification date will maintain/extend the Builder’s professional credential status by an additional three years.

2. Take and Pass the Current Builder Exam

Successfully completing the Builder exam will maintain/extend the Builder’s professional credential status by three years. 

If Builder Certification Expires:

  • A Builder who fails to meet one of the above requirements by their expiration date will be removed from the Builder database and their credential will no longer be considered valid.
  • A Builder whose certification status has expired can reactivate their certification by taking and passing the current Builder exam
